Weather in Central Highlands
Vietnam's Central Highlands are a distinct contrast from the tropical south, with an arid climate, rolling hills, and blue skies. The cool season in the Highlands runs between November and January, with temperatures averaging around 12 to 15 degrees Celsius. In February, March and April the mercury surges into the 30s. Come late April, early May, the rains begin and the temperatures begin to drop a little, with the monsoon ending in October. July and August are the wettest months.
Due to the Highland's elevated altitude, year-round the weather is cooler than on Vietnam's coast. Even in the hot season, mornings and evenings can be chilly and downright cold late at night. If you are planning on travelling by motorbike, keep these conditions in mind when packing as those morning chills will slice through a T-shirt with ease at 60km/h. The best time of year to visit the Highlands is between November and January, when the landscape is lush, the rain minimal and the weather temperate.
During the warming, dry months of February through April, the area can be parched and not particularly pleasant to travel in. By April, dust and haze are major issues, as can be bushfires (both intentional and natural). The rivers are low and the scenery is not as scenic, as the remainder of the year.
Across wet season, torrential rains can cause flash flooding. The dust turns to mud and getting around, particularly on the minor roads, slows down considerably. Through July and early August the rain can seem to be almost continual. If the rain and mud do not deter you, this is a good time of year to see the region at its lushest.
